Patent CA-2200113-A1 (CA)
Title: Mechanical/electrical displacement transducer
Inventor: JACOBSEN STEPHEN C
IPC: G08C21/00
Filed: 1990-10-03
Abstract: Displacement measuring apparatus for measuring the displacement and movement of an object includes a sensor having an operative surface and circuitry for producing an electrical output signal whose value is dependent upon the area of the operative surface covered by an electrical/magnetic field producing member.  The apparatus also includes an elongate, flexible band capable of producing an electric/magnetic field, where the band is attached at one end to the sensor to roll over and cover or unroll from over and uncover the operative surface as the object whose displacement is to be measured is moved.  The value of the electrical output signal produced by the circuitry is thus dependent upon the area of the operative surface covered by the band and thus by the position and movement of the object.

Title: Echo canceller
Inventor: HORIE NOBUYOSHI
IPC: H04B3/23
Filed: 1997-03-25
Abstract: A counter 160 increments a count value every given period. An adaptive operation control unit 90 selects channels in.which adaptive operation are done from all the channels in obedience to the count value to output produced selection signals to AND circuits 151 to 15n. Double-talk detection circuits 81 to 8n judge the presence of double-talk states and output detection signals to the AND circuits. The AND circuits operate logical AND of the selection signals and the detection signals and output the logical AND results as control signals to filter coefficient updating circuits 71 to 7n. The filter coefficient updating circuits update or do not update filter coefficients stored in FIR filter units 51 to 5n according to the control signals. The FIR filter units produce echo replicas by calculating convolutions of the filter coefficients and the receive signals. Subtractors 61 to 6n subtract the echo replicas from transmission signals to output residual signals.

Abstract: The Ice-Hockey-Puck Scoring System (IHPSS) discussed in this paper is a new inve ntion of an electronics device applying the latest technology of ferroelectric materials - L ead Lanthanum Titanate (PLT), Lead Zirconate Titanate (PZT) and Lead Magnesium Niobate (PMN) and theoretically proved, to provide easily the accuracy of the puck crossing the 2" of the 3-Dimensional-Goal-Line-Volume-Area (3DGLVA) in within lesser than IE-3m in all circumstances occurring in the professional games - interferences of bodies, glo ves and small metals. The IHPSS permits also to determine the puck velocities when it just cro sses the 3DGLVA. The IHPSS operates in DC electric fields. The electromagnetic theories developed permit to obtain any theoretical capacitance values (Farads). The mentioned ferroelectric materials permit to obtain the capacitance larger than 10.mu.F to comply with the selected Op-Amp current source. The device composes of four sets of hollow cubic-conductors Aji, Cji, Bji and Dj i as show in Figure-Current-Settlement-A),-B),-C) and Figure-One-Op-Amp-Per-9-Conductors-A),- B). All positive cubic-conductors have four sides with ferroelectric materials and the n egative ones have zero, one and two sides offerroelectric layers. Inside the puck contains thin plates of electrets as show in Figure-Puck-Model-I -a),-b),-c) and Figure-Puck-Model-II-a),-b). The quiescent beaming electric fields Aji to Cji, w hen they encounter the electret will provoke a variation in potential energy and permit t he Op-Amp to give out signals.

Patent CA-2218296-A1 (CA)
Title: Method and apparatus for storing and retrieving error check information
Inventor: TRANG DUC
IPC: G06F11/10
Filed: 1996-04-17
Abstract: A partial error check value for all preceding data in a sector is updated each time a new data item is written into a buffer (122) during a transfer from a host computer (110) to a system storage device (116).  The partial error check value is written into a buffer location following the location containing the most recently buffered data item from the associated sector. After the entire sector has been transferred the final check value for that sector will be available. Upon readback of a sector from the storage device (116), the sector size is longer by one data item since the appended check value is treated as the last data item. When the sector is read back, the check value is updated with the entry of each data item. When the access is complete, the stored check value is compared with the newly calculated value to determine whether an error has occurred.

Title: Synthesis of n-substituted oligomers
Inventor: RICHTER LUTZ
IPC: C08G69/10
Filed: 1996-06-04
Abstract: A solid-phase method for the synthesis of N-substituted oligomers, such as poly (N-substituted glycines) (referred to herein as poly NSGs) is used to obtain oligomers, such as poly NSGs of potential therapeutic interest which poly NSGs can have a wide variety of side-chain substituents. Each N-substituted glycine monomer is assembled from two "sub-monomers" directly on the solid support. Each cycle of monomer addition consists of two steps: (1) acylation of a secondary amine bound to the support with an acylating agent comprising a leaving group capable of nucleophilic displacement by -NH2, such as a haloacetic acid, and (2) introduction of the side-chain by nucleophilic displacement of the leaving group, such as halogen (as a solid support-bound a-haloacetamide) with a sufficient amount of a second sub-monomer comprising an -NH2 group, such as a primary amine, alkoxyamine, semicarbazide, acyl hydrazide, carbazate or the like. Repetition of the two step cycle of acylation and displacement gives the desired oligomers. Combinatorial libraries of cyclic compounds are disclosed wherein the cyclic compounds are comprised of at least one ring structure derived from cyclization of a peptoid backbone. The diversity of product compounds is generated by the sequential addition of substituted sub-monomers. Methods of synthesizing the combinatorial libraries and assay devices produced using the libraries are disclosed as is methodology for screening for and obtaining biologically active cyclic organic compounds.

Inventor: CHOE JOONHO
IPC: C12N9/90
Filed: 1996-09-12
Abstract: The Hepatitis C Virus (HCV) NS3 protein contains amino acid motifs of a serine proteinase, a nucleotide triphosphatase (NTPase), and an RNA helicase. A carboxy fragment of the HCV NS3 protein was purified and possessed RNA helicase activity. Defections from the amino terminus resulted in the protein becoming soluble. Deletions from the carboxy terminus do not result in a loss of helicase activity until at least 50 amino acids are deleted, the helicase activity requires ATP  and divalent cations such as Mg2+ and Mn2+. The helicase activity was blocked by monoclonal antibody specific to the HCV NS3 protein.
